how to send property value as a message sent by multiple object?
As ZargulTheWizard mentioned, the only way to receive the body text/values at run-time is with Python API. However, you could use a different setup, that being to send a simple &quot;buy.100&quot; message as you showed above, than, on the object(s) that are meant to be receiving the messages vie message sensors, have them use a property actuator with type &quot;copy&quot; to copy the &quot;value&quot; property to and fro the sending/receiving objects. You'll also need to have a game-property with the same type (e.g boolean, integer, float) on the receiving object(s).
